Abstract
A method for processing a dispersion-hardened platinum composition is provided. A three-dimensional body of a dispersion-hardened platinum composition containing at least 70% by weight platinum and maximally 29.95% by weight other precious metals, as well as 0.05% by weight to 0.5% by weight of at least one partially-oxidized non-precious metal selected from zirconium, cerium, scandium, and yttrium is provided and cold formed, whereby the cross-sectional area of the three-dimensional body is reduced by maximally 20% during the cold forming, Subsequently a temperature treatment is performed on the cold-formed three-dimensional body, in which the cold-formed product is tempered at at least 1,100° C. for at least one hour. A method for producing a product made of a dispersion-hardened platinum composition, a dispersion-hardened platinum material obtained according to the processing method, and the use of a dispersion-hardened platinum material are also described.
